Gravity works, and I can see it especially in older homes when I perform the gravity check - insulation slips inside walls!
This house was built in 1951. And I see this all the time.
Doing a thermal sweep around the house each room demonstrated exterior walls that looked something like this.
Cavities that were not completely insulated.
Certainly by todays' standards the insulation put into houses in the 50s was minimal.
And it is likely they didn't staple it up inside the walls.
But it is quite evident here where insulation has slipped, come loose, pulled away from the drywall, or perhaps deteriorated over time.
Outdoors it was 35F at this moment. Inside the house it was quite comfortable.
The coolest spots on that wall registered 47.7F in this room.
And this was so in every single room.
Yes, gravity works! It pulls things down. Or away. If something deteriorates over time gravity will scrunch it up!
Until the advent of thermal cameras we simply didn't know how much a wall can be made insulation free. I have seen tall, balloon walls where virtually 1/3 was without insulation, it having slipped so much.
My recommendation: have your walls checked! Hire a thermographer, who are all really cute, to come by and look around! Weak insulation can be improved, and efficiency can be regained. At least to a point!
